What is the meaning of "heavenly glories" in obituaries among Christians, and what is the ruling of religion on eulogizing Christians with these words, whether verbally or in writing?

It is not permissible for a Muslim to mourn Christians with the phrase "he/she passed on to heavenly glories," because it implies testifying to their deserving of mercy and Paradise, which is Islamically forbidden. Indeed, Islamic scholars have unanimously agreed on the disbelief of anyone who does not consider Christians disbelievers or doubts their disbelief. Furthermore, it is forbidden to ask for mercy upon a disbeliever, according to the text of the Quran and scholarly consensus, and no soul enters Paradise except a Muslim soul. As for the soul of a disbeliever, its destiny is to a prison in the lowest earth, and the gates of heaven are closed to it.
